The EGR cooler reduces exhaust gas temperature before recirculation into the engine, improving emissions and engine efficiency. However, EGR coolers are prone to internal blockage from carbon accumulation and can develop coolant leaks that cause serious engine problems. At Metre Per Second, we provide complete EGR cooler services including diagnosis, cleaning, repair, and replacement. Our experience includes all types of EGR coolers from simple single-pass designs to complex multi-pass coolers used in modern diesel engines. We understand the critical importance of proper EGR cooler function for engine health and can advise on the best approach - whether cleaning, repair, or replacement - based on your cooler's condition.

EGR System — Your Questions Answered
Updated 2026-08-09 with fresh answers from our specialists.
What specific tools and diagnostic equipment do you use for EGR cooler repair in KPHB, Hyderabad?
At Metre Per Second, we utilize OEM diagnostic tools like the Bosch KTS series to accurately diagnose EGR cooler issues. For physical repairs, we have specialized tools such as EGR cooler cleaning kits and high-pressure testing equipment to check for leaks. Additionally, we often use OBD-II scanners to retrieve fault codes related to the EGR system, which helps us determine the exact problem efficiently.
What are the common causes of EGR cooler leaks in diesel engines, and how can I diagnose them?
Common causes of EGR cooler leaks include corrosion due to high exhaust temperatures and vibrations from engine operation, particularly in high-performance diesel engines like those from Tata or Mahindra. To diagnose, we check for OBD codes such as P0401 or P0403 and perform a pressure test using OEM tools like the Snap-on Solus. In KPHB, regular inspections can help catch these issues early, particularly in vehicles driven in congested traffic conditions.
How long does an EGR cooler repair usually take in your workshop?
On average, an EGR cooler repair or replacement can take between 3 to 5 hours, depending on the complexity of the job and the specific vehicle model. For example, larger diesel engines may require additional time for proper access. Scheduling an appointment can help us expedite the process.
Can I clean my EGR cooler myself, or should I rely on professional cleaning services?
While it's possible to clean an EGR cooler yourself using specialized cleaning solutions, professional services are recommended for thorough cleaning. We use OEM-approved tools and techniques to ensure all carbon deposits are effectively removed, restoring optimal function, especially in high-traffic areas like KPHB.
How much should I budget for EGR cooler replacement in Hyderabad?
The cost for EGR cooler replacement can vary widely, typically ranging from INR 8,000 to INR 20,000, depending on your vehicle's make and model. Brands like Mahindra and Tata may have different pricing due to OEM parts availability. Always check with local suppliers in Hyderabad for specific quotes.
What symptoms indicate that my EGR cooler might need repair in my diesel vehicle?
Common symptoms of a failing EGR cooler include noticeable coolant loss, white smoke from the exhaust, and poor engine performance. You may also experience an illuminated check engine light, often linked to OBD codes like P0401 or P0420, indicating EGR flow issues. If you're in KPHB, consider visiting us for a thorough diagnosis.

Customer Reviews — EGR Cooler Repair in Hyderabad
4.8 / 5 from 1,084+ verified reviews.
I took my Mahindra Scorpio to get the left-hand quarter panel painted after some scratches and dents from a minor incident. From the moment I stepped into the workshop in Sainikpuri, Hyderabad, I could tell I was in good hands. The team thoroughly inspected the damage and provided an honest estimate of ₹8,000, which was significantly lower than the dealership's quote of ₹12,500. They explained the whole process, including the type of paint they would use and the importance of matching the color perfectly. I was pleasantly surprised with the results! The paint job was flawless, and my car looked as good as new. They completed the work within 2 days, which was quicker than I expected. Overall, I’m extremely satisfied and will definitely return for any future needs. I highly recommend this workshop to anyone looking for quality service without breaking the bank!
I recently took my Ford Freestyle to get the clutch set replaced, and overall, I had a positive experience. The car was showing signs of difficulty shifting gears and I was worried it might be more than just the clutch. The team quickly diagnosed the issue and explained that it was indeed the clutch set that required replacement. They quoted me ₹15,000, which was significantly cheaper compared to the authorized dealership price of ₹22,000. My only mild complaint was the slight delay—my car was ready an hour later than initially promised. However, the quality of the work was reassuring, and I could feel the difference immediately. I would recommend their service to others and will likely return for future needs.
I took my Citroen Basalt in for a comprehensive service at Metre Per Second in ECIL. The car was showing inconsistent behavior, particularly with the braking system, and I was hoping they would pinpoint the issue. While they did manage to fix the brake problem, which involved changing the brake pads and rotors, I had to go back for an additional fix a week later as the engine light came on again. The initial quote was around ₹15,000, but the final bill came to ₹18,500 due to some additional work needed on the exhaust system. Overall, the quality of service was decent, but I found the need for a revisit quite frustrating. I might consider going back for routine maintenance, but I’m not entirely convinced after this experience.
I recently took my Mercedes Benz AMG GT to get a manual carbon cleaning, and I couldn't be happier with the results. The engine was showing a slight performance drop, and after some research, I figured it could be due to carbon buildup. The technicians at this workshop conducted a thorough diagnosis and identified the issue promptly. They explained the carbon cleaning procedure and provided a detailed quote. What impressed me the most was the pricing — at just ₹7,000, it was much cheaper than what authorized dealers were quoting around ₹15,000. After the service, my car felt brand new, and the performance was back to its peak. I will definitely recommend their services to friends in ECIL and will be returning for future maintenance needs.
I took my Mercedes Benz EQC for wheel balancing at a workshop in Nagole, hoping for a smooth ride. Initially, the team was helpful in diagnosing a subtle vibration I had been feeling at higher speeds. They suggested balancing the wheels and also checked the alignment, which was slightly off. However, the process took longer than I expected—over four hours, even though I was told it would be done in two. When I picked up the car, the vibration had noticeably reduced but wasn’t completely gone, prompting me to wonder if I need to return for the adjustment again. They charged me ₹2,800, which seemed reasonable compared to a dealer’s estimate of ₹4,500, but the slight delay and incomplete fix have left me uncertain about my next visit. Overall, it was a decent job, but I might look for other options next time.
I recently took my Fiat Adventure to get a steering rack repair, and I must say, the experience was fantastic. The steering had developed a strange noise, making it difficult to drive, and I was worried about the potential costs. However, the experts diagnosed it quickly and efficiently. They explained that the rack had developed a leak and needed replacing. The service was not only thorough but also fairly priced, coming in at just ₹18,000 compared to the ₹25,000 the authorized dealer quoted. I appreciated their transparency throughout the process and the professional manner of the staff. After the repairs, my steering feels as good as new, and I can’t thank them enough. I will definitely recommend this workshop to friends in Nagole.
